Title: Phenolic resin compositions
Inventor: LEMON PETER HERBERT RICHARD BR
IPC: C08G8/36
Filed: 1990-03-13
Granted: 2000-01-11
Abstract: A phenolic resin composition comprises an ester-curable phenol-aldehyde resin in alkaline aqueous solution wherein the phenol-aldehyde resin is a methylolated phenolic novolak resin. Preferably, during manufacture of the methylolated phenolic novolak resin, unreacted phenol is removed. The composition may be employed, for reaction with an organic ester hardener, as a binder in the production of foundry moulds and cores having high strength. The further incorporation of an aryloxy alcohol in the novolak resin binder additionally improves the final strength of products obtained by a gas curing technique using ester vapour, such as that of methyl formate.

Abstract: A progressive die apparatus and method for cold forming weld adapters. A progressive die apparatus, preferably having at least four working stations and several idle stations, is used to form weld adapters from rectangular bar stock having a thickness of at least about 3/8 inch. Plain-carbon steel bar stock material or other weldable metal material is successively fed through the progressive die apparatus, which is preferably installed in a knuckle-joint power press. The cold forming method includes the following steps: (a) at a first working station piercing the first hole; (b) at a second working station coining the stock material in the area surrounding the first hole to define a collar-like configuration including a hollow region for receiving the fastener; (c) at a third working station re-piercing said stock material to remove material that was displaced into the first hole during the coining step; (d) successively advancing stock material from the first to the last working stations; and (e) at a fourth working station cutting the stock material after steps (a) through (c).

Title: Encryption apparatus
Inventor: FREEBURG THOMAS A
IPC: H04L9/24
Filed: 1991-02-25
Granted: 1995-10-03
Abstract: An encryption circuit that operates with substantially zero delay. Using programmable keys and polynomials, the encryp-tion algorithm can be constantly changed to thwart any unintended receiving parties from decoding the data. A key (101) and a polynomial (102) are loaded into registers. The key is then loaded into a shift register and shifted through XOR gates (106) at a programmable rate. The other input of the XOR gates comes from the result of ANDing (103) a disable signal, the polynomial register (102), and the last stage of the shift register (104). Eight bits of the shift register outputs are XOR'ed with the input data to be encrypted. The output of these XOR gates (105) is the encrypted data.

Title: Integrated optics device mounting for thermal and high g-shock isolation
Inventor: RODINO VINCENT D
IPC: G02B6/30
Filed: 1991-10-08
Granted: 2002-02-19
Abstract: An integrated optics (1O) chip comprising an optical signal path disposed in a principal plane of a crystalline chip having a known chip thickness, anisotropic thermal characteristics, and crystallographic orientation, is mounted to a first surface of a si-milar thermally anisotropic crystalline material substrate. A second surface of the substrate, spaced from the first surface at a sub-strate thickness approaching the known chip thickness, is bonded to a mounting surface with a pressure sensitive acrylic film adhesive. Employing this adhesive allows a substantial reduction in the thickness of the substrate as compared to the thickness of the IO chip while allowing vibration and high G-shock loads to be imparted on the structure without affecting the electro-optical properties of the 1O chip.

Abstract: 2115552 9303910 PCTABS00020 A process for producing an energy absorbing panel having at least one energy absorbing surface in a mold comprising an upper mold and a lower mold. The process comprising placing a reinforcing layer in at least one of the upper mold and the lower mold. A  liquid foamable polyurethane composition is then dispensed in the lower mold. The upper mold and lower mold are closed to define an enclosure corresponding substantially to the energy absorbing panel, the liquid foamable polyurethane composition is expanded to fill substantially the enclosure to produce a resilient polyurethane foam core which adheres to the reinforcing layer thereby providing an energy absorbing surface. The reinforcing layer has a tensile strength greater than the tensile strength of the resilient polyurethane foam core. Upon compression of the panel at the energy absorbing surface to about 50 % by volume of the uncompressed panel in a direction substantially normal to the reinforcing layer, the panel recovers to at least about 90 % of volume of the uncompressed panel in less than about 30 minutes. The panel has widespread utility and is particularly useful in vehicular applications.

IPC: G07C9/00
Filed: 1992-11-30
Granted: 2004-06-22
Abstract: A lock (19) which by physical or logical means controls human access to an objective (29) such as a restricted area or a computer system is controlled by a data processing system (10) which has access to a store of authorised users (14) and a store of complex images (15), specifically images of human faces. Each authorised user knows certain ones of the complex images, and these key images are linked to an identity statement unique to that user. On receipt of an identity statement signifying an authorised user, a matrix of images including the key images is presented to the user on a display (12), and by means of a suitable input device (20) the user must identify which images are his key images in order to confirm authorisation and be permitted access. The user and image stores (18) may be carried in credit card form as a section of an optical disk. The high security of the system results from the inability of a person to communicate adequately to another the ability to recognise a third person or other complex image.

Title: Center wind assist mechanism in secondary position
Inventor: KREMAR DJURO
IPC: B65H19/22
Filed: 1995-01-26
Granted: 2002-08-13
Abstract: A center wind assist mechanism is provided for use in a web winding device for winding a substantially continuous web onto a reel bar rotating about its center axis. The winding device includes a driving drum that maintains a first nip engagement with the reel bar to rotate the reel bar and transfer the web passing over a surface of the driving drum onto the reel bar.   The winding device also includes a secondary arm for engaging the reel bar to maintain the reel bar in nip driving engagement with the driving drum. The center wind assist mechanism comprises a drive assist support arm mounted to the secondary arm to move therewith. The center wind assist mechanism also includes a driving wheel rotatably connected to one end of the drive assist support arm. The center wind assist mechanism further includes tensioning apparatus, a center assist drive and transmission. The tensioning apparatus is connected to the drive assist support arm to maintain the driving wheel in driving and torque transfer relation with a peripheral surface portion of the reel bar which peripheral surface portion is off center to the center axis of the reel bar between the center axis and the driving drum. The center assist drive rotatably drives through a transmission the driving wheel. The use of the center assist drive mechanism insures that a driving assist is provided by the driving wheel. Further, the location of the driving wheel in the off center location does not add to the nip pressure being applied by the secondary arm which could adversely effect the web being wound onto the reel bar.
